1140V Mechanical Medium Voltage AC VFD Drive for Blowers

Blowers are widely used in cement, textile and steel plants. We take the blowers in clean room for example.

A clean room is virtually dust and/or bacteria free. Clean rooms are used in laboratory work and in assembly or repair of precision equipment. A clean room fan supplies clean air through ventilation systems. This fan runs a system that filters exterior air, maintains temperature and humidity at constant levels, and circulates the interior air through a high-performance air filter while expelling part of the interior air.

Application Challenges

·Maintain positive pressure in the clean room.

·Maintain a high quality filtering system at all times.

·Avoid mechanical resonance in the surrounding equipment.

·Detect clogged fans or air ducts automatically.

Features of G11 matching blower application

Features	Benefits
Open Loop Vector and V/Hz Control with Torque Compensation	Provides excellent breakaway torque for thick materials and constant torque to maintain mixing speeds under heavy loads.
Preset frequency reference	Preset mixing patterns can be established for different materials.
Auto-Restart after momentary power loss	Mixing can quickly restart after fault or momentary power loss. This keeps perishable foods from spoiling in process.
Power loss Ride-Through	The mixing process in not interrupted during brief power loss (< 5 ms).

Tips:

A variable-frequency drive (VFD) is a system for controlling the rotational speed of an alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor. A variable frequency drive is a specific type of adjustable-speed drive. Variable-frequency drives are also known as adjustable-frequency drives (AFD), variable-speed drives (VSD), AC drives, microdrives or inverter drives. Since the voltage is varied along with frequency, thes
